AUTOMATIC MUSICAL INSTRUMENT.

SPECIFICATION fcrmig part 'of Letters Patent No. '713,053, datedNovember 11, 1902.

Application filed June 2, l900. Serial No. 18,827. (No model.)

To ctZZ whom it may concern:

Be it known that I, GUsTAv A. BEACH- HAUSEN, a citizen of the UnitedStates,- residing at Rahway, Union county, State of New Jersey, haveinvented certain new and useful Inprovements in Automatic MusicalInstruments, of which the following is a specification.

My invention relates more particularly to automatic musical instruments,and is directed to mechanism forcontrolling the number of automaticOperations which may be given'at each operation of the starting-level'or starting mechanism-that is to say, the invention has for its objectto provide mechanism which in the present instance nay be set to permita tune to be played any desired number of times upon a single movementof the starting-lever or starting mechanism and which will cause theinstrument to be automatically stopped when the tune has been played thepredeternined number of times.

The invention will be found of great advantage in Coin-controlleddevices wherein a movement of the starting-lever or starting mechanismcan only be effected with the aid of a coin. The employnent ot'nyinvention in musical instruments, for instance, Will enable the ownerof the instrunent to set it to play a tune one or more times upon theinsertion of each coin, so that the number of times a tune is played byeach coin depends upon the predeternined arrangement of the mechanism bythe owner thereof.

To these ends my invention consists in the novel arrangement andcombination of parts hereinafter described and claimed.

In the drawings, Figure 1 represents acentral vertical sectional view ofan automatic musical instrumentembodyingmyinvcntion, the section beingtaken from front to rear of the instrument. In this View portions of thedevice have been omitted for the purpose of clearer illustra-tion. Fg. 2is an eularged detail rear elevation of a portion ot' the nechanism tobe hereinafter described. Fig. 3 is a transverse vertical sectional Viewof the same, taken on theline 3 3 of Fig. 2 and looking in the directionof the arrow in said figure. Figs.

4 and ll are detail side views of portions of the device to behereinafterdescribed. Fig. 5 is a detail side View of a portion of themechanism to be hereinafter described. Fig. 6 is a front view of thesame. Figs. 7 and S are detail face Views of certain portions of therepeating mechanism to be hereinafter more fully described. Fig. 9 is afragmentary detail rear view of portions of the repeating mechanism,together with the parts with which they coperate. Fig. 10 is adiagrammatic view ot' the motorcontrolling mechanism. j

Referring specifically to Fig. 1 of the drawings, it will be observedthat the instrument is contained within an inclosing casing 1 and that asuitable note-sheet carriage 2 is adapt- ,ed to reciprocate in oppositedirections therein to bring the note-sheets to a position to be conveyedto operative position in the instrument. The mechanism for et'fectingthe movenent of the carriage consists in the present instance of a lever3, which is connected to a link 4, which in turn is connected to thecarrage 2. upper end thereof carries an antifrictionroller 6, whichextends into an internal endless cam 7. i The cam 7 is pivoted at 8 andis rigidly connected to a gear 9, which meshes with a coperating gear10. The gear 10 receives an intermittent rotary notion from a gear 11,that is moved intermittently by suitable pawl ll which hasmovenentimparted thereto by a spring-motor 12. This carriage maylikewise be moved by hand in order to bring the desired sheetinto thepath of the conveying meclanism in any desired mannersuch, for instance,as described in prior patents granted to me. The note sheet or diskwhich it is desired to play having been moved 'by the carriage into thepath of suitable conrveying mechanism 12 will at the' proper time beconveyed up into the operative position, when by mechanism which is tobe hereiuafter described the spring-motor 12 will be automaticallystopped and ,the motor 13 will be automatically set in operation toefiect a playing movement of the sheet. After the desh-ed number ofplaying movements ot' Theplever 3 is pivoted at 5, and the the sheet hastaken place the spring-motor 13 is automatically stopped and thespring-motor 12 is set in operation to convey the sheet back into itsrespective position in the car- -iage. i When the note-sheet has beenraised into the operative position, the note sheet or disk pivot-pin 14will-be automatically projected through a central bearingtherein and theclamping-rod 15 will be -simultaneously moved, so as to bring theantifriction-rollers' 16 thereon into contact with the sheet, and thusclamp it into operative position. The

- mechanism for elfecting this movement ot'the position.

pivot-pin and clamping-red will now be briefly described. Themovablepivot-pin 14 is adapted to be reciprocated in a suitable hearingby a link 17, which is connected to an arm 18, fixed upon a rock-shaft19. Movement is transmitted to this rock-shaft 19 by the cams 20 on thespring drum or motor 12 contact- 'ing with a roller carried upon an arm21, fixed upon the rock-shaft 19. (See Figs 2, 3, and ll.) Thisrock-shaft 19 is likewise provided with arms 22, (sec Fig. 2,) eachofwhich contacts .with an abutment 23, carried upon each of the'rods 24.The rods 24 extend from the rear toward the front of the machine, wherethey are connected to the clamping-rod 15. The clamping-rod 15 is movedto the freeing position (illustrated in Fig. 1 of the drawings) bycoiled springs 25, which surround said rods 24 and tend to force theclamping-rod outwardly. v

It will be understood from the foregoing description that an oscillationofthe rock- 12 is arrested and the motor 13 is permitted torevolve amove ment will be transmitted to the.

driving-wheel from said last-mentioned motor to etfect a playingmovement of the sheet. It will be understood that this playing movementof the sheet Will bring aqout a playing operation, which in the presentinstance 'consists in transmitting movement to suitable star-.

wheels, which vibratc the tongues of one or more suitable steel combs26. (See Fig. 1.) It will be underslood that any suitable mechanism maybe employed for conveying the hote-sheets to and from operativeposition.

In the' present instauce I have illustrated in' Fig. 1 bifurcated conveying-fingers 12 ,which` are noved up and down upon the guide-rods 27therefor by the fiexible connections 28,

which are connected to said fingers. These fiexible connections or bands28 are in turn connected to band-pulleys 29, which are fixed upon theshaf-t 30. This shaft 30 likewise has fixed thereon a band-pulley 31',to which is connected a flexible connection or band 32. The opposite endof this band 32 is connected to a lever 33, as indicated at 34. Thelever 33 is pivoted to a fixed pintle, as indicated at 35, and has anoppositely-extending depending arm -36, whichcarries'anantifriction-roller 37, that is adapted to :bear upon thecam38, which is carried by the `drum 12. It will thus be seen that arotation of the drum 12 will cause the lever 33 to be vibrated onitspivot, thus moving the band 32 and transmitting motion to the shaft 30and to the fleXible connections28, which are connected to the pulleys 29upon said shaft, thereby effecting the raisig and lowering of thebit'urcated fingers 12 and conveying the notedisks to and from operativeposition in the instrument. Each of the motors 12 and 13 is likewiseprovided with a coperating governor 39 and 40, respectively, whichcontrol the movement of said motors and are themselves stopped andpermitted to rotate by suitable stop-arms. Thus the governor 39 isprovided with two stop-arms 41 42, which are adapted to contact with anarm 43, carried by the governor, whereas the governor 40 has acoperatingstop-arm 44, which is adapted to contact with an 'arm 45, carried by thegovernor 40. Suitable intermediate mechanism between the spring-motors12 and 13 is provided for setting one motor in operation when the otheris stopped I will now proceed to describe this intermediate controllingmechanism for the'motors.

Special reference being had to the diag'am- ICQ matic view shown in Fig.10, it will be seen that the spring-drum 12 is provided with op-`positely-disposed recesses or notches 46 47 in a cam-track 48. Thiscam-track 48 is on the periphery of the drum, and a lever 49 is adaptedto coperate therewith. The lever 49 is connected by a pin-and-.slotconnection 50 to an arm 51, which is rigidly connected to the stop-arm41. The lever 49 is provided with a second arm 52, which is connected toa spring 53, which normally maintains the nose of the lever 49 incontact with the cam-track 48 on the drum 12. The relation of the,parts'just described is such that when the instrument is in a state ofrest, as illustrated in Fig. 10 of the drawings, the nose of the lever49 will bedepressed bythe spring 53 into one of the notches ordepressions 46 47 in the cam-track 48 and the stop arm or lever 41 willbe projected into the pat-h of the coperating'arm 43 of thegovernor 39,thus maintaining the motor 12 against movement. The stop-arm 42 isrigidly connected to an arm 54, which in turn is pivot-ally connected toa link 55. This IIo' link 55 is pivoted at its opposite end to the stoparm or lever 44, as indicated at 56. The pivot 57, which connccts thearm 54 to the link 55, extends into a slot in the piece 58 (see Fig. 10)and forms a connection between said arm and link and the piece 58, whichlatte'r I term a controlling-piece. This controllingpiece 58 is adaptedto oscillate upon a pivot 59 and is provided at one end with a nose 60and upon the opposite end with the nose 61. It will thus be seen thatthe position of the controlling-piece 58 determines the positioning ofthe stop-arms 42 and 44-that is to say, if it elfects a movement of thestop-arm 42 in the direction of the arrow in Fig. 10 it will cause thearm 44 to be projected into the path of the arm 45 of the governor 40.The nose 60 of this controlling-piece 58 is adapted to bear upon acam-track 62 on the periphe'y of the spring-drum 12 and at intervals tobe depressed into either of the oppositely-disposed depressions 63 64 insaid cam-track. The nose 61 upon the opposite end of thiscontrollingpiece 58 is adapted to coperate with a camtrack 65 and to beforced at intervals into one or the other of the oppositely-disposeddepressions 66 67 in said cam-track. The positioning of thecontrolling-piece 58 is deternined by a spring-pressed pin 68, which isbifurcated at its end, so as to straddle and bear upon one edge 69 ofsaid controlling-piece and to exert a pressure thereon through the'spring 70. This pin 68 and its spring are carried by an oscillatingpiece 71, which is pivoted at 71 Connection is made between the piece 71and the lever 72, which is pivoted upon the rod 59. This pivotalconnection between the piece 71 and the lever 72 is indicated at 73. Thelever 72 has an arm 74, that is adapted to project into the path of apin 75 upon the spring-drum l3 and to be operated thereby to shift thepiece 71 to one side of the pivot 59 of the controlling-piece 58, asrepresented in Fig. 10 of the drawings. This movement of the lever 72causes a pressure to be exerted upon the upper end of thecontrolling-piece 58 to depressthe nose 61 thereof into one or the otherof the depressions 66 67 in the cam track 65 when a depression isbrought opposite the nose. This movement of the controlling-piece 58causes the stoparm 44 to be projected into the path of the arm 45 on thegovernor 40 to arrest its movement. Then, however, the piece 71 has beenmoved upon its pivot to the opposite side of the pivot 59 of thecontrolling-piece, a pressure will be exerted upon the lower end of thecontrollingpiece to force the nose 60 thereof into one of thedepressions 63 64 when the same arrives at a point opposite the nose.This movement of the controlling-piece 58 forces the arm 42 into thepath of the arm 43 of the governor 39 to arrest its movement andsimultaneously withdraws the arm 44 from the path of the arm of thegovernor 40, thus releasing the governor 40 to permit a free movement ofthe notor 13. The mechanisn for effecting a movement of the piece 71 ina downward direction to bring about this lastmentioned movement of theparts comprises an arm 76, connected to a rook-shaft 77. This'ock-shat't 77 is maintained in the nornal position by a spring 78,fixed at one end to a sleeve 79, carried by said rock-shaft, and at itsopposite end to a pin carried by a fixed sleeve 80. This roek-shaft 77is likewise provided with a depending arm 81, (see Fig. 3,) which isadapted to project into the path of suitable abutments 82 83, carried bythe spring-drum 12. that each half-revolution of the drum 12 will causea movement to be transmitted to the arm 81 and to the rock-shaft 77.This oscillation of the rock-shaft 77 in the manner described causes thearm 76 to depress the piece 71, thereby causing a spring-pressure to beexerted upon the lower arm of the controlling-piece 58.

Upon reference to Fig. 10 of the drawings it will be observed that asuitable startinglever 84 is connected to the stop-arm 41 of thegovernor 39. This starting-lever maybe of any suitable Construction andis controlled from the outside of the inclosing casing either by meansof the insertion of a coin or by suitable connection therewith of otherauxiliary levers. (Not shown.)

In order to efect an operation of the apparatus, motion is transmittedto the startinglever 84 by neans of the insertion of a coin in theinstrument or otherwise to move the lever or stop-arm 41 in thedirection of the arrow in Fig. 10. This movement of the stoparm 41permits a free rotation of the governor 39 and at the same timewithdraws the nose of the lever 49 from the recess 46 or 47 in which itwas lodged. The release of the governor 39 permits the rotation of thespringdrum 12, and when the starting-lever has been released the noseupon the lever 49 will bear upon the highest portion of the camtrack 48and will prevent the stop-arm 41 from returning to the normal positionuntil the nose of the lever 40 again arrives at one of the depressions46 47 in the cam-track 48. During this movement of the drum 12 from onenotch 46 to the other notch 47 an abutment 82 or 83 will be brought intocontact with its cope'ating arm 81 (see Fig. 3) and will oscillate theshaft 77, thereby moving the arm 76 and depressing the free end of thepiece 71, so that it will exert a pressure upon the lower end of thecontrolling-piece 58. hen this depression of the piece 71 has takenplace, the nose 60 of the controllingpiece 58 will be forced into anotch or depression 63 64 when the same arrives opposite said nose. Thismovement of the nose 60 into a depression in the cam-track 62 causes thestop-arm 42 to be projected into the path of the arm 43 of the governor39 to arrest its movement, thereby stopping the notor 12. At this sameinstant and by the same movement motion will be transmitted through thelink 55 to the stop-arm 44, and said stop-arm will be withdrawn fronithe arm 45 of the governor 40, when the motor 13 will be free to move.The rotation of the motor orspringdrum 13 will bring the pin 75 thereoninto contact with the arm 74 on the 1ever72, thereby moving the piece 71to exert a spring-pres- It will thus be understood ICO IIO

site the nose 61, when it will be depressed into the notch or depressionand will force the stop-arm 44 into the path of the arm 45 of thegovernor 40, thereby arresting further movement of the spring-drum 13.By this same movement of the controlling-piece 58 motion istransmittedto the stop-arm 42 to withdraw the same from the path of the arm 43,earried by the governor 39, and the motor 12 will be free to rotate.lion of the motor 12 will bring a depression 46 or 47 opposite the noseon the lever 49 and` willpermit a movement of the nose into thedepression, thus forcing the stop-arm 41 into the pathof the arm of thegovernor 39, thereby In the present instance the device com-' prises apointer 85, secured to a stationary portion ot' the instrument. vCoperating with this pointer 85 is a dial 86, provided with numbers, asindicated at 87, that are adapted r to register with the pointer 85.These numerals correspond to the number of repetitions which theinstrument is capable of making, twelve being shown ,in the presentinstance, though it is obvious that any suitable number may be provided.This dial 86 is pivoted at 88 and is free to be rotated when disengagedby the looking mechanism. This locking mechanism comprises in thepresent instance a spring-pressed looking-bolt 89, the free end 90 ofwhich is adapted to take into any one of the series of openings 91.which correspond in number to the number of playing Operations which theinstrument is capable of performing for each operation of thestarting-leven Thus the lockingbolt is adapted to lock the dial in anyone of twelve positions to bring-any one-of the twelve numerals onthedial opposite to the pointer 85. Upon the inner face of the dial 86 is alaterally-extending pin 92. Adjacent to and upon the same pivot as thedial 86 is mounted a' ratchet-wh eel 93. This ratchet-wheel haslaterally-extending pins 94, which are one less in number than thenumber of playing operations capable of' being performed by a singledepression of the starting-lover. From an examination of Fig. 7 of thedrawings it will be seen that these pins 94 are equidistant apart, andthat a blank space has been left at the point indicated by the numeral95, and that one tooth is provided upon the ratchet- A movement ofthespring-drum space95.

This coiled spring is connected at one endto the pin 96 and at' its opposite end to the pin 92, so that when theratchet-wheel is turned with relation to the dial the spring will exerta pressure tending to rotate the ratchet-wheel in the direction of thearrow in Fig; 7. When the ratchet-wheel is free to rotate, it will becaused to move around its pivot by the spring 97 until the pin 96 comesin contact with the pin 92 upon the dial, when the movement of theratchet-wheel will be arrested. Coperating with the teeth of the ratchetwheel 93 is a pawl 98, whereas a pawl 99 coperates with the pins 94 uponsaid wheel. The two pawls are connected to move together and are nountedupon the' rockshaft 77.

From an' inspection of Fig. 7 of the drawings it will be observed thatthe blank space 95 of the ratchet-wheel is on the same' radial line withthe pin 96, and 'the pin 92 being on substantially the same radial lineas the numeral 10 on the dial will cause the pin-96 to be arrested atthis point, so as to bring the blank space of the ratchet-wheel oppositethe 'numeral 10 on the dial. This being the case the blank space 95 onthe ratchet-wheel will be under the pawl 99 when the dial is set so asto bring the numer-al l ii into register with the pointer, as indicatedin Fig. 3. The drum 13 is provided witha laterally-extending pin 100,which rotates with the drum and in each rotation thereof is adapted toengage one of the teeth of the ratchet-wheel, as indicated in Fig. 3 ofthe drawings, so as to transmit an intermittent rotary motion to said'ratchetwheel. The eXtent of this movement transmitted to theratehet-wheel corresponds substantially to the space between' two teeththereof, and the movement of the ratchetwheel transmits motion to therock-shaft 77 through a pin 94 on the ratchet-wheel coming in contactwith the pawl 99. This movement of the rock-shaft 77 is effective toforce the piece 7l of the controlling mechanism to the lowermostposition through the arm 76, as has been herenbefore described. As soonas the pawl 99 is released from the pin 94 which transmitted movementthereto said pawl Will be forced by the spring 78 between said pin andthe next succeeding pin, and the nose of the pawl 98 will be broughtinto engagement with the next succeeding tooth of the ratchetwheel andwill prevent the ratchet-wheel from being rotated in the direction ofthe arrow, Fig. 7, to itsnornal position by the action of its spring 97.It Will be nnderstood that a movement is transmitted from' the ratchet--wheel 93 through its pins 94 and the pawl 99 and shaft 77 to thepiece71 at each intermit- IIO tent mvement of the ratchet-wheel transmittedby the spring-drum 13 and that as long as the piece 71 is maintained inthe lowermost position, so as to exert a pressnre upon the lower end ofthe controlling-piece 58, the motor 13 will continue to operate. Thenumber of Operations transmitted to the rock-shaft 77 and the piece 71will depend upon the number of pins 94 which operate upon the pawl 99before the blank space 95 is reached. When this blank space 95 isreached, the ratchetwheel 93 will receive movement from the spring-drum13 in the usual manner, but no movement will be transmitted to the pawl99 by reason ofthe absence of the pin at the point 95. The piece 71willtherefore be allowed to remain in the elevated position, where ithas been moved by the pin 75 on the drum 13 Contacting with the arm 74of the-level' 72, so that a further rotation of the drum 13 will bringone of the notches 60 67in to register with the nose 61 on thecontrolling-piece 58, thereby permitting the nose to be depressed in therecess or depression to eifect an arrest of the governor 40 and itsmotor 13 and to permit a movement of the governor 39 and its motor 12.The movement of the motor 12 will bring one of the reccsses 46 47opposite the nose of the lever 49, and the governor 39`will be stopped,thus bringin" the entire mechanism to a standstilll I? will therefore beseen thata movement of the dial 86 from left to right will carry with itthe ratchet-wheel 93 and that the relative position of the blank space95 on the ratchet-wheel to the pointer 85 willdetermine the number ot'playing operations. Thus if the dialis rotated to bring the nnmeral 12thereon opposite the pointer 85 it will require a complete revolution ofthe ratchet-wheel before it is turned to a point where the blank spacethereon arrives at the pawl 99. When this blank space arrives at thepawl 99, no motion will be transmitted thereto, and consequently nomotion will be transmitted to the finger or arm 76, so that the piece 71will be-allowed to remain in the uppermost position, where it has beenmoved by the lever 72, and the motor 13 will be arrested in the. mannerhereinbefore described, after which the motor 12 will be set inoperation and after having performed its several functions will bebrought to a standstill. The final operation of the motor 12 will causean abutment 82 or 83 thereon to contact with the depending arm 81 on therockshaft 77, thereby moving said rock-shaft and the pawls 98 '99 to thedotted-line position represented in Fig. 7 of the drawings. It will beobserved that this position of the pawls entirely frees theratchet-wheel from engagement therewith and that it is free to berotated to the normal position by its coiled spring 97. The nextoperation of the starting lever or mechanism 84 ot the device willtherefore bring about twelve repetitions of the piece to be played, andso on at each operation of the starting-level'.

or motor mechanism 12 and 13 may be of any desired Construction and maybe wound up from the exterior of the instrument in any suitable manner.In the present instance I have illustrated a winding-pinion 101., whichis connected to a winding-post 102, said pinion 101 meshing with awinding-gear 103, which is suitably connected with the inner end of thespring to wind the drum 12. The drum 13 is wound by a suitablewinding-post 104, which carries at its inner end a pinion 105, thatmeshes with an internal gear 106. The periphery of this gear 106 isprovided with or formed as a ratchet-wheel107, which ratchet-wheel isengaged by a pawl 108 to prevent a backward movement thereof. Thecombined ratchet-wheel and gear 107 106 is connected to the inner end ofa spring contained wit-hin the spring-drum 13 in any suitable nanner, soas to wind the same. drum 12 carrics a driving-gear 109, that transmitsmotion to a train of gear 110, that operates the governor 39. Thespring-drum 13 is likewise provided with a driving-gear 111, whichcoperates with a train of gear 112, that transmits notion to thegovernor 40 of the spring-motor 13.

From the foregoing description itis thought that a clear understandingot the Construction and operation of the various parts of the apparatusmay be arrived at without a further description of the operationthereof.
